The damage of the motor includes two aspects, the damage of the stator winding and the bearing damage.
This kind of damage usually occurs in a few weeks to ten months, the specific time and the brand of the inverter, the motor brand, the motor power, the carrier frequency of the inverter, the cable length between the inverter and the motor, the ambient temperature Many factors related.
Early damage to the motor to the production of enterprises to bring huge economic losses. This loss is not only the cost of motor repair and replacement, more important is the economic loss caused by accidental shutdown. Therefore, when using the inverter to drive the motor, it is necessary to pay enough attention to the problem of motor damage.
